Fancy. Derived from French word, bourgeoisie, which means middle class. They were never content on being the middle class and strived for the best...the upper
FANCY class.
Therefore...Boojie = fancy or
wannabe fancy. (Depends on what or who it is aimed at).
Ex:* Sees a girl with knee-high fur leather
boots*
"Dang girl, you boojie!"
Ex: Dude #1: "I CANNOT eat chicken wings with my fingers."
Dude #2: " Well look at you Mr.Boojie!"
